Pretty cool, and some of it is equally fascinating when you read it "backwards". For example the USA government spends as much money to power it's military ships as it does on robots. That's gotta be a lot of diesel.. And the USA porn industry is a bigger market than the service robot industry in the entire world, and twice as big as the industrial robot market in the world. It would've been more impressive if the USA robot industry was compared to the USA porn industry. Well I suppose it's no surprise that porn is huge :)
